Specification forming part-f Letters Patent No. 9.1221; dated J nly13,1352.

To all when?, tm/ay concern/ 5 Be it known that I, J ACOB Gr". vVVINGJR,of Vicksburg,in the county of Varren and `State of Mississippi, haveinvented c ertain new and useful Improvements in Cotton and otherPresses; and I do hereby declare that the following 4is a fullJ clear,"and exact description thereof, reference being had to the annexeddrawings, and to letters of reference marked thereon, making a part ofthis specification, in whieh Figure 1 is a side elevation of the pressshown in position to' receive the cotton to be pressed. Fig. 2' isavertical longitudinal section through the center, (the screws and baleof cotton being in elevation,)`showing the` r epressed and bound;

*E The nature of' my invention consists 1n co1 1- left-hand screws, -ortwo left-.hand and one right, as hereinafter described, so as to givethree times the progressive motion to the follower in the same timethatwould be' effected by a single screw, and so arranging it that theentire weight of the frame and chamber of the press is made effective toaid in pressing the bale. v

To enable others to make and use my invention and operation. A isastrong, heavy-frame, ,which receives female screwsB B', placedvertically thrpugh the center of each, and in line with each other, theone at the top having a right-hand thread, that at the bottom aleft-hand' one;

C is the cross-head ofthe fellow-er, and slides on .vertical 4guide-rods c. Said cross-head Ais also provided with a left-hand femalescrew, D, through its center inline 'with those marked B B in thetopand'bottom of the frame.

E is a left-hand screw, forming a permanent standard, secured to theflooring of the room, -and over which the female screw B' (in the lowerpart of the press-frame) turns.` On the top of this screw E is pivotedthe bed-plateF of the press, which is of thedesired length and breadthof the "bale, and fits loosely in the ychamber G, and is chased withgrooves f in the bale while in the press.

' II is the' follower,corresponding in size and form with the.hed-plate, and has grooves h' in its face.- This follower is suspended,face downward,'by the slings I I from the cross-head C.

' J J is a screw ofthe same diameterand number of threads to the inch asthe screw E. It is cut from its center downward left-handed, and screwsthrough the rfemale screw D in the cross-head, and from the centerupward it is cut right-handed, and screws through the female screw B inthe upper'part of the frame, and at its upper end is rmly attached-tolthe slidingA cross-beam K. This cross beam is provided with verticalguide-rods L-one at; each end-which may be erected in forxnoi` agallows, as shown, or more generally attached 4to the framingcf thebuilding. ..Asit is commenlLunderstood thailctlpai can be pressed intoone-fourth of its bulk, I propose to make the chamber G of the ordinarylengtlrand breadth of Aa bale of cotton, and of four times its depth7andthe screws J, J, and E each to travel through its respective nutone-fourth of the depth of said chamber.

Thus, when the bed-plate and follower are screwed up to the closestpitch, there will be one-fourth of the depth of the chamber he,

tween them to be occupied by the-bale'of cotton when pressed. s Inoperating this machine the frame must be firstrturned on the screws asfar they will permit,`travel1ng round to .the right, which will elevatethe frame A until its lower cross beam strikes the under sideof thebed-platev F, while by the action of the right-and-left screw J J theupper cross-beam ef the frame and the crosshead G will bebroughtiii'contact with cach other, in whichpositi'on the follower H isat libertyto swing clear of the top of the .chamber G, which "is then to be -lledwith cotton and trampied in', the `.cloth being put over and under intheusual manner. lThe follower H is to'loe brought backv inA itsposition over the chamber, and the frame turned on the screws b y horse,steam, or other power, traveling to the left, by which the frame will bescrewed down on the screw E, the chamber sliding over the vbed-plate F,which revolves with the chamber on thetop, of saidscrew. At thesame-time, bythe actien of the right-and-left screwY- J J', the'fol'ilower H will travel double'the distance inte thetop end .of thechamber.'

Thus the twp plates F and. H both act as followers in pressing on thetop and bottom of the bale, and the follower is madeto perform adistance toward the bed-plate of three-fourths the depth of the 'chambenwhile the frame, to which the power is applied, is turned over a screwof one-fourth said depth of chamber, which is consequently effected inone-third of the time required -bylthe ordinary single-screwv press,andthe entire weight of the framew'ork being thrown upon the screw E, ittravels downward as on receive another supply of cotton, as beforedescribed. It is deemed unnecessary to specify `at length thatright-hand screws may be substituted for the left-hand ones, and alefthand one in place of the right-hand screw, the effect of whichrwouldsimply be to reverse the travel ofthe frame in pressing the bale andclearing 'or-elevating the follower.

This form of press is equally applicable for baling-hay, hemp', hops,&c.

Having thus described my invention, what I claim therein as new, anddesire to secure by Letters Patent, is-

1. The arrangement and combination of the screws J, J', and E with thetop and bottom cross-beams ofthe frame andthe cross-head of thefollower, by which the follower and bedplateare made to press the balefrom top and bottom, ,and the distance traveled by the follower towardthe bed-plate is three times that of the frame-(to which the power isapplied) over the screw. y

2. Making the weight of the press and auxiliary power by resting itentirelyon the lower screw, E, sothat in pressing the bale the frame istraveling down the screw as onan inclined plane.

' In testimony whereof I have hereunto signed my name before twosubscribing witnesses.
